Methods, systems, apparatus including computer programming encoded on a computer storage medium for efficiently storing data across memory hierarchy on one or plurality of nodes include creating ordered partitions of data based on key where partition order is achieved using highly space optimized prefix tree index. Within a partition, data is fully or partially ordered based on key. Multiple prefix tree indices are created one for each memory hierarchy and all are stored in fast memory like DRAM. Data is merged or moved from faster memory to slower memory in the hierarchy as the space is used up. Checkpoint mechanism along with WAL provides recovery guarantee and data snapshots. Distributed data storage systems like databases/key value stores can utilize this data storage mechanism to store and retrieve data efficiently across memory hierarchy on one or plurality of nodes.

The present invention is a method and system for measuring a set of shopper behavior metrics that represent the strength of a product category or a group of categories in the performance of a store area. A set of rating parameters are defined in order to provide a unified and standardized rating system. The rating system represents the effectiveness of the product category in a store area. The metrics are defined in a manner that is normalized so that they can be used across different types of product categories. The datasets are measured per category or group of categories over time to identify how the strength has varied over time, and to monitor trends in the category performance. The measured datasets are further analyzed based on various demographic groups and behavior segments. The analysis facilitates a better understanding of the strength of the category for different shopper segments, which in turn can be applied for developing better store area optimization strategies.
